I can also confirm the issue occurred on and after kernel 6.2, and
confirm the workaround setting btrfs discard iops_limit works for my
device:

08:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
NVMe SSD Controller PM9A1/PM9A3/9
80PRO

I had to use ~6000 for my device, instead of 1000.
I'm currently on kernel 6.2.1.

I am also interested to know what if this is expected.
